Meggitt Sensing Systems (San Juan Capistrano) has introduced the Endevco® model 8530C series of high-sensitivity piezoresistive absolute pressure transducers, offering high output and a non-linearity of 1% at 3x over-range in a highly compact (3.86 mm face diameter) package. Offered in ranges of 15, 50 and 100 psia with 225 mV full scale output and high resonant frequencies of 180 kHz (15 psia), 320 kHz (50 psia) and 500 kHz (100 psia), the Endevco® model 8530C series features an active four-arm strain gage bridge, diffused into a sculpted silicon diaphragm. The volume behind the diaphragm is both evacuated and glass sealed to provide an absolute pressure reference. The transducers also feature integral temperature compensation, providing stable performance over a temperature range of -18°C to +93°C (0°F to +200°F). Units are supplied with an integral cable, with custom lengths available upon request. A 10-32 UNF-2A mounting thread is standard, with an integral four-pin connector available with the “M37” option.
